[libcxx] [test] Fix get/put long_double_ru_RU on Glibc, FreeBSD and Windows

[mstorsjo]

Summary

Note, reducing ios.width() in put_long_double instead of using variable
padding, when using a variable width symbol. Some of those tests didn't
actually trigger any padding in the existing form, with a longer
currency symbol; reduce the width so there's no actual padding with the
slightly shorter currency symbol either.

The tests for the international currency symbol use the same amount of
padding on all platforms, so they still exercise the padding properly.

53

Would it make sense to move this function to a helper header and share the code between the two tests?

56

Please reduce the scope to the loop.
Please use a lower case i.

61

std::iswdigit requires <cwctype>.

[mstorsjo]

libcxx/test/std/localization/locale.categories/category.monetary/locale.money.get/locale.money.get.members/get_long_double_ru_RU.pass.cpp

53

I guess that could be done - we have the same in the get/put long_double fr_FR tests too (but with slightly different constellation of separators across systems). Do you have a suggestion on where to place it?

56

Ok, can do. This is based on copypaste from the existing fr_FR tests though. But if we move the helper out somewhere, we could do the same cleanup at the same time.

61

Thanks, good catch!

[mstorsjo]

Sharing the convert_thousands_sep helper function in a new header, locale_helpers.h, across {get,put}_long_double_{fr_FR,ru_RU} tests.

[mstorsjo]

Trying to fix failures in the no-wchar configuration.

[Mordante]

LGTM!

libcxx/test/std/localization/locale.categories/category.monetary/locale.money.get/locale.money.get.members/get_long_double_ru_RU.pass.cpp

53

I would suggest under test/support, but I see you already did that.

[• Quuxplusone]

No strong objection to it as-is, but I think there are improvements possible.

libcxx/test/std/localization/locale.categories/category.monetary/locale.money.get/locale.money.get.members/get_long_double_ru_RU.pass.cpp

97

Consider whether this can be simply

std::string symbol = "\u20BD";
~~~
std::string symbol = "\u0440\u0443\u0431.";

435–437

As above, can this use \u instead of \x?

libcxx/test/std/localization/locale.categories/category.monetary/locale.money.put/locale.money.put.members/put_long_double_ru_RU.pass.cpp

96–98

As above. I'm also starting to wonder if you now have a convenient place to hang LocaleHelpers::russian_currency_symbol(). :)
(Or currency_symbol_ru_RU() or whatever naming convention you like.)

[mstorsjo]

Factorize the platform differences for the currency symbol from the curr_symbol test into LocaleHelpers, use unicode code points instead of individual utf8 bytes in the strings.

[mstorsjo]

Fixed the no-wide-chars configuration.

[• Quuxplusone]

Let's do one more round, just to see if MultiStringType is useful.

libcxx/test/support/locale_helpers.h

74 ↗

(On Diff #412333)

I wonder if you could use MultiStringType instead of std::string here, and then you wouldn't need to repeat yourself on lines 90-108.

76–82 ↗

(On Diff #412333)

The comments are just repeating what the code says.
(The only reason I don't also comment on the "\u0440\u0443\u0431" line is that I can't think of a short yet enlightening comment to put, except for // "руб", and I don't want to encourage non-ASCII comments.)

[mstorsjo]

Factorize currency_symbol_ru_RU() to use MultiStringType, applied the suggested cleanups (removing redundant comments, adding unicode char explanations).

[• Quuxplusone]

LGTM % one last comment! I think MultiStringType really cleaned it up nicely.

libcxx/test/support/locale_helpers.h

48–54 ↗

(On Diff #412526)

I think this will be easier to grok. (It follows the same pattern as lines 76-83 below.)

[mstorsjo]

Fix the use of MultiString in the curr_symbol testcase.

Hello,

I see the following failures with this commit:

Sorry about that. It would seem like there are differences in the ru_RU.UTF-8 locale in your installation than in the ones used in CI and in my local environment. What glibc version are you running (as it would seem we require to selectively expect different results on different versions of glibc)?

Can you rerun the put_long_double_ru_RU.pass.cpp test with this diff applied?

What glibc version do you have? As you're on RHEL, I would expect an older one (mine is on Ubuntu 20.04, with glibc 2.31). There seems to be differences in most fields, in particular in mon_decimal_point here. We already have some conditionals due to the fact that currency_symbol differs for ru_RU.UTF-8 in various glibc versions (apparently with the new form appearing in 2.24), but we never had any glibc conditionals for the differing mon_decimal_point. As that probably would require quite intrusive changes to the test, I guess it's probably best to make the test bail out on such older versions (as it just has been XFAILed forever on that platform before anyway).

Seems like it 2.17. ldd on the bult binary says e.g.

I dug around and found that this change stems from https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=f11f2f6e145d6fc6b52f6b0733599f8b96595733, and that commit was part of the 2.27 release.
